3 Claims. (Cl. ,M -218)` My invention aims to provide improvements insnap fastener sockets.

In the drawing which illustrates a preferred embodiment of myinvention:-

' l Figure 1 is a section through a snap fastener 1c carrying mediumengaging surface; and

Fig. 3 is a plan View of the socket showing that face from which thestud enters.

Referring now to the specific embodiment of my invention, as illustratedby the annexed drawing, I have shown a socket structure which isparticularly adapted for use on wearing apparel and other articlesadapted to be laundered. The two most important objects of my inventionare to provide a socket having a relatively small stud-receivingaperture with a relatively large support-engaging surface and to providewithin the socket casing a structure which will prevent crushing of thecasing.

The particular socket illustrated includes a one-piece sheet metalcasing part having a rear face 1, a front face 2 spaced from the rearface 1 and connected at its outer periphery by a wall 3, as bestillustrated in Figure l. The front face has a stud-receiving aperture 4of small diameter compared to the diameter of the casing and isintersected by a split ring spring 5, as best illustrated in Figs. 1 and3. Between the spring 5 and the wall 3 (Fig. l) I have provided anintegral double wall 6 extending from the rear face 1 toward and againstthe inner surface of the front face 2. This wall 6 is spaced inwardlyfrom the peripheral wall 3 thereby to provide means for properlypositioning the spring 5 with relation to the aperture 4. This wall alsoprevents accidental crushing of the casing during the laundering processof the article to which it is attached or at any other time.

By usingi a double wall 6 and an outer peripheral Wall 3, spacedtherefrom laterally, I provide an additional area 7, outside of thesurface 1 heretofore provided, thereby to increase the area of thesurface 1 which may come in contact with the material to which thesocket is to be attached.

The particular socket shown is secured to a flexible carrying medium 8(Fig. 1) by a rivet 9 carried by a suitable cap member 10. 'Ihe rivet 9extends through the carrying medium 8, through a hole 11 in the surface1 of the socket surface of the back face 1.

Any suitable stud member may be used according to the particularformation of the casing and the spring used in conjunction therewith.The stud installation illustrated includes a stud member 12 secured toone side of a carrying me- @o dium 13. by means of a suitable attachingmember 14, the base of which is shown in Figure 1.

My improved socket is particularly desirable because it will withstandav relatively great amount of crushing stress without injury.Furthermore, because of the additional fabricengaging surface providedby the structure described above, a relatively large cap 10 may be usedin combination with the casing thereby gripping a large enough area ofthe carrying 1o medium 8 so that the carrying medium will not tear loosefrom between the cap and the socket when lateral stresses are exertedthereon.

While I have illustrated and described a preferred embodiment of myinvention I do not wish to be limited thereby because the scope of myinvention is best defined by the following claims:

1. A snap fastener socket comprising a hollow stud-receiving casing partformed from sheet s@ metal and having a stud-receiving aperture at oneside thereof, a stud-engaging spring located in said casing andintersecting said stud-receiving aperture, said casing part having acontinuous one-piece front face surrounding the stud- 8,5r receivingaperture, a back face spaced therefrom,

a peripheral wall connecting the two faces .of the casing and meanslocated inwardly from said peripheral wall and entirely between thefaces to support said faces and prevent accidental crushing of thecasing part thereby to maintain the proper spacing for operation of saidspring. j

2. A snap fastener socket comprising a hollow stud-receiving casing partformed from sheet metal and having a front face and a back face spacedfrom each other, a stud-receiving aperture in the front face, a springlocated in said casing and intersecting said stud-receiving aperture, awall extending from one of said faces toward and into engagement withthe other face and surrounding said spring, a return bend oi'v said wallextending back to the face with which it is integral, a portion ofsaidface extending outwardly from the return bend of said wall in the planeof the other face portion with which said wall is integral to increasethe area of said face and a peripheral wall portion connecting saidoutwardly extending portion and the other face at the edge of saidcasing.

3. A snap fastener socket comprising a hollow stud-receiving casing partformed from sheet metal and having a rigid frontface 2 provided with astud-receiving aperture 4, aback face 1,

`a. peripheral wall 3 connectingV said front and back faces, a doubleWall 6 extending from ysaid rear face toward and into engagement withsaid front face andbeing located inwardly from the as y' 1
